Embodiment Construction

[0012] As shown in Fig. 1, the gas drying device mainly includes a cooling dryer 1, a dehumidifying dryer 2, and a compressor part 3 in this embodiment.

[0013] The dehumidifying dryer 2 uses a pressure box 4 type. The pressure box 4 has a drying zone 5 and a regeneration zone 6 with adsorption and / or absorption media 7 which are alternately guided through the drying zone 5 and the regeneration zone 6.

[0014] In addition, the device also includes a primary circuit 8 including pipes having parts 8A, 8B, 8C, 8D, 8E, 8F, 8G, 8H, 8I, 8J, and 8K, the above-mentioned cooling dryer 1, the dehumidifying dryer 2 and the above-mentioned The compressor part 3 is connected to the primary circuit 8. The primary circuit 8 makes it possible to compress the gas to be dried first, then at least partially dry it in the cooling dryer 1 and then lead it through the dehumidifying dryer 2 The drying zone 5 can be further dried.

[0015] The device also includes a secondary circuit 9, which serves as...

Abstract

Gas drying device, consisting of a desiccant dryer ( 2 ) which makes use of a pressure tank ( 4 ) with a drying zone ( 5 ) and a regeneration zone ( 6 ), wi than adsorption and / or absorption medium ( 7 ) which is alternately guided through the drying zone ( 5 ) and the regenerat ion zone ( 6 ); a primary circuit ( 8 ) in which the abovement ioned desiccant dryer ( 2 ) is included, which makes it possible to guide the gas to be dried through the drying zone ( 5 ) of the desiccant dryer ( 2 ); a secondary circuit ( 9 ) which makes it possible for a part of the gas to be dried to be guided through the regeneration zone ( 6 ) of the desiccant dryer ( 2 ) and to absorb moisture there, characterised in that the device also contains a cooling dryer ( 1 ) which is inserted upstream the abovement ioned desiccant dryer ( 2 ) in the primary circuit ( 8 ).

Description

Technical field [0001] The invention relates to a device for drying gas, especially for drying compressed gas. [0002] In particular, the present invention relates to a device for drying gas. The device contains an appliance called a dehumidification dryer. The dehumidification dryer utilizes a pressure tank with a drying zone and a regeneration zone, and the tank is equipped with adsorption and / or absorption The medium is led alternately through the drying zone and the regeneration zone. Background technique [0003] A known problem with such devices is that, for example, under extreme environmental conditions in the tropics, the gas is always not sufficiently dried for all required uses. [0004] In the case of high temperature and high humidity, the regeneration capacity of this desiccant dryer is indeed exceeded. [0005] In addition to dehumidifying dryers, cooling dryers are also widely known, but cooling and drying in tropical environments is either inefficient or leads t...
